WATER-EVAPORAIOR FO R STOVES.

SDECIFICATIO forming part of Letters Patent No. 309,772, dated December 23, 1884.

Application lcd January 23, 1884.

T all whom it may concern:

Beit known that I, CHARLES T. Davis, of the city of Baltimore and State 0f Maryland, have invented certain Improvements in Vater-Evaporators for Stoves, of which the i'ollowing is a specication.

In carrying out my invention I apply to a stove in various ways an open vessel containing water, having thimbles therein, through to which heat radiated from the stove passes to the apartment. The evaporator is not in full contact with the heated surface of the stove, but is provided with Bauges or projections, which serve to insulate the vessel,and thereby prevent direct conduction of heat to the water. By this isolation of the vessel the water is less liable to boil and give off superabundance of steam or vapor. rIhe iianges also serve to provide a hot-air chamber between the evaporator and the stove, from which the heated air passes uniformly through the thimbles to the apartment.

In the further description of`1ny invention, reference being had to the accompanying drawings, forming a part hereof', in Which- Figure I is a perspective view of a stove provided with my improved evaporator. Fig. II is a vertical section of my evaporator and portions of the stove on an enlarged scale.

3o Fig. III is a top view ofthe evaporator,also

on an enlarged scale. Eig. IV is a partlysectional view of an evaporator modified in construction, and illustrating` a different mode of applying the invention to a stove. Figs.

' 35 V and VI are exterior views, as seen from different points, of an evaporator adapted for application to a flat surface of a stove.

A is the stove proper, and B the waterevaporator, which in Figs. I, II, and III con- 40 sists of a shallow cylindrical pan, a, having` a central opening, b, for the escape of vapor,

and thimbles c, for the passage of heated air (No mod el.) Y

from the stove to the apartment. In the said figures the evaporator is constructed so as to be applicable to the top of the stove, and when so applied itis preferably covered by an ornamental perforated cover, C, which admits ofthe escape of the moistened air to the surrounding atmosphere. A flange, D,which surrounds the bottom e of the evaporator, forms, in connection with the said bottom and the stove-top j', a chamber for hot air, and also serves to isolate the vessel from the hot plate |f, and prevent the too rapid heating ot' the water.

In Fig. IV the evaporator is in the form of a jacket which surrounds a part of the stovecylinder.

The evaporator shown in FigsV and VI is flat, and adapted for application to a stove having a similar surface.

I disclaim in this case the invention described by mein an application for Letters Patent for an improvement in hot-air registers and water-evaporators, iiled January 23, 1884, under No. 118,405.

I claim as my inventionl. As a new article, a waterevaporator adapted for application to a stove, which consists of a vessel with an open top, having the 7o front and rear sides perforatethand connected by thirnbles which are inserted in the said perforations, substantially as speciiied.

2. In combination with a stove, a waterevaporator having an opening at the top, thimbles extending through it for the passage of hot air, and a ange to separate the evaporator from the surface of the stove, and thereby form a chamber for hot air, substantially as specified.
